Success of interview largely depends on the traits and qualities of interviewer. But there is no universally accepted list of qualities of a good or successful interviewer. However, some of the important requirements/qualities/traits of a successful interviewer are mentioned below:

Knowledge about the job: A good Interviewer is one who has sufficient knowledge about the job for which he/she is taking the interview. If the interviewer lacks adequate knowledge regarding job duties, responsibilities, and qualifications required. It would not be possible by him to select the best candidate.

Training and experience: Interviewers should have adequate experience and necessary training to conduct interview, effectively and efficiently.

Listening attentively: Good interviewers are attentive listeners. They listen more than they talk. The listening tendency helps the interviewer to make better evaluation. Many interviews fail because the interviewer talks more than listening.

Emotional Maturity: The interviewer should be free from biasness and undue emotion. He should have the ability to judge the situation based on logic and wisdom.

Control of anger and aggression: Control of anger, arrogance, or aggression is a very important trait of successful interviewers. They should not be aggressive or intimidating. They should neither miss-guide the candidate nor should react to the applicant’s comments. When the candidate strays from the track of inquiry, good interviewer guides him back to the point.

Stable personality: Personality is the way through which one can create impression in the minds of others. Good interviewer possesses such a stable personality so that he/she can treat all the interviewees in the same general way. He should not show any inclination to any particular interviewee.

Extrovert behavior: Extrovert behavior is another quality of a good interviewer. This quality helps the interviewer to be conversational, frank and friendly in nature.

Physical stamina: Sound mind goes with good health. The interviewer should possess good physical and mental health so that he can work at a stress with a huge number of interviewees.
